Specifically synthesized grades designed to comply with European REACH standards and Spanish environmental regulations (MITECO).
Navigating Iberia's Hydrological Reality, Environmental Directives, and High-Performance Polymer Requirements.
Spain faces severe structural water stress, particularly in Southern and Eastern regions such as Andalusia, Murcia, Valencia, and Catalonia. Driven by the Spanish National Hydrological Plan and strict EU Directive 2020/2184 on water quality, municipal wastewater treatment plants (EDARs) and industrial facilities are required to implement tertiary treatment systems capable of extreme solid-liquid separation clarity.
Qingdao Oubo Chemical provides ultra-high molecular weight Anionic Polyacrylamide (APAM) specifically tailored for rapid settling, low dosage footprint, and zero toxic monomer residual (<0.05%), enabling seamless compliance with Spanish water reuse standards for agricultural irrigation and industrial cooling.
As the world's leading producer of olive oil, Spain generates millions of cubic meters of highly concentrated, recalcitrant wastewater (alpechín/alpechuza) rich in polyphenols, organic matter, and suspended solids. Traditional biological treatment fails under high COD/BOD loads.
Our specialized APAM formulations act as high-efficiency coagulant aids and primary flocculants when paired with inorganic salts. They break emulsified lipids and aggregate colloidal organic suspended solids in physical-chemical primary treatment, yielding high-clarity effluent and dense sludge suitable for mechanical dewatering.
In Andalusia (Huelva, Seville), the reactivation of polymetallic mining operations along the Iberian Pyrite Belt requires high-performance sedimenting polymers for copper, zinc, and lead tailings clarification. Acidic drainage and heavy metal precipitation demand high-salt-tolerant Anionic Polyacrylamide.
Oubo's tailored APAM polymers exhibit exceptional chemical stability across wide pH spectra (pH 3 to 12), ensuring accelerated sedimentation rates, reduced turbidity in thickeners, and clean water recycling back to process circuits.
Northern Spain's robust packaging and paper manufacturing hubs demand retention aids, drainage aids, and dry-strength agents that reduce fiber loss and lower energy consumption during thermal drying.
Oubo's medium-to-high charge density APAM resins enhance hydrogen bonding between fibers and fillers, boosting sheet strength while accelerating water drainage on high-speed Fourdrinier and twin-wire paper machines.
Scientific alignment of molecular weight (MW) and anionicity (charge density) for optimal operational efficiency.

|---|---|---|---|---|---|
| Oubo APAM 18M-HD | Anionic | 18 - 22 Million | 25 - 30% (High) | ≥ 88% | Municipal Wastewater Clarification & Agricultural Soil Conditioning |
| Oubo APAM 20M-MD | Anionic | 20 - 25 Million | 15 - 20% (Medium) | ≥ 89% | Mineral Tailings Settling & Mining Wastewater Clarification |
| Oubo APAM 15M-LD | Anionic | 12 - 16 Million | 5 - 10% (Low) | ≥ 88% | Alpechín / Food Processing Wastewater & Paper Retention Aid |
| Oubo APAM Super-High | Anionic | 22 - 28 Million | 30 - 40% (Ultra High) | ≥ 90% | Brine & High Ionic Strength Industrial Effluent Separation |
Oubo Chemical employs advanced enzymatic biological methods for monomer synthesis. Unlike traditional chemical nitrile hydration, biological catalysis avoids heavy metal impurities (such as copper residue) and produces ultra-pure Acrylamide monomer, resulting in linear PAM chains with higher molecular weight and superior water solubility.
Our APAM operates via dual mechanisms: charge neutralization and interparticle bridging. Long polymer chains extend into solution, adsorption onto particle surfaces, forming giant, dense flocs ("macro-flocs") that settle rapidly under gravity with minimal shear breakage.
Designed with optimized micro-crystalline granule sizes (20–80 mesh), Oubo APAM dissolves completely within 40–50 minutes under standard stirring. This eliminates "fish-eye" agglomeration, reducing equipment clogging and polymer consumption by up to 15-20%.
Direct supply capabilities from the Free Trade Zone of Qingdao to Valencia, Algeciras, and Barcelona ports.
Qingdao Oubo Chemical Co., Ltd. secures top-tier acrylonitrile raw materials through strategic partnerships with global petrochemical leaders like SINOPEC and Eni. Located strategically within the Free Trade Zone of Qingdao, China, our facilities benefit from seamless logistics, zero-tariff bonded raw material processing, and direct access to major ocean freight lanes directly connecting to key Spanish entry ports (Valencia, Barcelona, Bilbao, and Algeciras).
Every batch of Polyacrylamide undergoes rigorous 3-tier Quality Control (QC) inspection prior to dispatch, including intrinsic viscosity testing, monomer residual HPLC analysis, and dissolution rate testing. We ensure strict adherence to EU REACH registration standards, ISO9001:2008 quality systems, and ISO14001 environmental guidelines, protecting Spanish distributors and industrial end-users against regulatory supply chain interruptions.

Optimized polymer chemistry for wastewater treatment, papermaking, oilfield, and mining operations.
In municipal sewage treatment and industrial effluent systems across Spain, APAM functions as a high-performance primary settling agent and secondary clarifier aid. It accelerates sedimentation in DAF (Dissolved Air Flotation) systems, reduces chemical sludge volume, and optimizes dewatering efficiency on belt presses and decanter centrifuges.
Used as an anionic trash scavenger, retention agent, and dry-strength additive. Oubo APAM binds short fibers and inorganic fillers (calcium carbonate, titanium dioxide) into the fiber web, preventing raw material loss in white water streams and improving paper tensile strength.
For Spanish hydrometallurgical plants, APAM provides fast settling rates in thickeners and counter-current decantation (CCD) circuits. It ensures clear overflow water for immediate process recirculation while producing dense underflow sludge for safe dry-stacking.
Applied in Spanish agricultural sectors (Almería, Murcia, Andalusia) to combat topsoil erosion, reduce soil crusting, and increase water infiltration in furrow and drip irrigation systems. Minimizes irrigation water run-off by stabilizing soil aggregate structure.
